Last month, the international “Campaign to Stop Killer Robots” was officially launched in London. The Initiative, backed by groups from ten countries and several international NGOs aims at pre-emptively banning autonomous robots, most importantly autonomous unmanned aerial vehicles (UAVs or “drones”). In the press statement, the initiators claim that “[u]rgent action is needed to pre-emptively ban lethal robot weapons that would be able to select and attack targets without any human intervention”. They call for “an international treaty […] national laws and other measures.” Nobel Peace Laureate Jody Williams argues that “[a]llowing life or death decisions on the battlefield to be made by machines crosses a fundamental moral line and represents an unacceptable application of technology.”
